there is no driver or flash tool in that zip, only the image.I'm a new to flashing, I have no tools/drivers I have a Crown and would like to update it's rom, can you please post a link to mtk drivers and to the flash tool.

ps. will there be an android 5.x for Crown, they are still being sold I got mine 2 days ago, they are powerful phones it would be good to have an updated OS for them.
